Just put water in my pool last Tuesday, so it has been a week. Currently I am adding a gallon of 10% chlorine a day to my pool with a CYA of 30. The pool gets direct sunlight all day long. Is there a recommended CYA level so I am not using quite so much chlorine each day? I am currently adding chlorine at night before sundown and it goes to 6 and by the same time next day it is 2 before adding more. Thanks.
